1 Claim.

This invention relates to improvements in discharge chutes for hay balers, the primary object in view being to equip pick-up hay balers with efiicient means of simple, inexpensive construction for transferring bales of hay, or straw, from the baler to a trailing truck while the baler and I truck are in motion, and which is especially adapted for embodying in standard types of pickup hay balers without necessitating material alterations in the basic equipment of the balers.

Other and subordinate objects, also comprehended by this invention, together with the precise nature of the improvements and the advantages thereof, will become readily apparent when the succeeding description and claim are read with reference to the drawing accompanying and forming part of this specification.

In said drawing:

Figure 1 is a fragmentary view in side elevation illustrating the improved discharge chute in a preferred embodiment thereof applied to a pick-up hay baler pulling a trailer truck,

Figure 2 is a view in top plan of the discharge chute detached,

Figure 3 is a view in transverse section taken on the line 3+3 of Figure 1 and drawn to an enlarged scale,

Figure 4 is a detail view in vertical section taken on the line 4-4 of Figure 1 and drawn to an enlarged scale.

Referring to the drawing by numerals, this invention has been shown therein as applied to a well known type of pick-up hay baler I, conventionally illustrated a sufficient for the present purposes, and which, at its discharge end, is formed with upper and lower side frame members 2, 3 connected by uprights 4 and forming a guide frame for bales of hay, or straw, 5 discharged; under pressure, in a well known manner out of said rear end. This improved chute 6 is designed for attachment to said rear end of the baler I to form a bridge between said end of said baler and the bed 1 of a trailer truck 8 of the type equipped with a tongue 9. I

The chute 6 is of elongated, generally rectangular form and embodies a pair of side bars ID' of angle iron form opposed with channel sides facing to form tracks for the discharge bales 5, and intermediate cross bar I I "and end bars I2 suitably connecting the bars I II together in parallel relation, and side walls forming members I3 relatively narrower than said bars I0 and fitted in said bars III, as best shown in Figure 3, in

upstanding position. Preferably, a longitudinal reinforcing bar II is provided in the center of the chute and connected to said bars II, I 2, a by rivets I4. The side wall-forming members I3 may be similarly connected to the bars III, as at I5.' As will be noted, particularly in Figure 3, the cross bars II, I2 underlie the bars I0 and the reinforcing bar I3 overlies said cross bars so that said bar I3 provides a center clear track for the bales 5. At what constitutes the front end of the chute 6, the bars I0 are bowed downwardly to obviate an abrupt rise at the discharge end of the baler I and obstruction to passage of the bales 5 into said chute, and the lower edges of said members [3 are correspondingly curved. Preferably, the side wall-forming members l3 taper edgewise to the rear end of th chute 6 and the bars III at said rear end are downwardly curved, as at IS, with the end cross bar I2 correspondingly shaped to reduce frictional resistance to discharge of bales 5 out of said chute.

For attaching the chute -6 to the baler I, a pair of hanger bars, one of which is shown at H, are bolted, as at I8, to the lower side members 3 of said baler l at the discharge end of said baler to depend below said members 3. At the front end of the chute 6, bolts, as at I9, are extended through the front ends of the bars I0 and said members I3 and through the lower ends of said hanger bars I! with nuts 20 thereon, said bolts I9 forming pivots whereby the chute is vertically swingable on said hanger bars II. Preferably bushings, as at 2|, are provided around the'bolts I9 and in said bars In and members I 3 to obviate wear in said bars Ill and members I3. A pair of opposed strap iron bars 22 are riveted to the side wall-forming members I3, as at 23, intermediate the ends of the chute 6 and to each of which a rod 24 is pivoted, as at 25, at one end of the rod, the other end of the rod being provided with a chain adapted to be hooked over a hook plate 21 suitably attached to the appropriate upper frame member 2 of the baler l in upstanding position. As will be seen,

the chains 26 are attached to the hook plates 21 so that the chute 6 inclines upwardly and rearwardly from the baler I and the angle of inclination of the chute 6 may be varied by attaching difierent links of the chains 26 to said hook plates 21.

A coupling bracket 28 inclines downwardly and rearwardly from the cross bar l2 at the front end of the chute 6 and is provided with an up-' standing coupling pin 29 over which a suitable coupling sleeve 30 on the front end of the tongue 8 is adapted to be disposed. Said cross bar I2, it will be noted, is disposed in the rear of the ing through the chute 6 oil the rods 20, chain 26 and hook plates 21. As will be understood, the chute 6 is or the proper length to dispose the rear end thereof over the front end or the bed I of the trailer truck I.

The manner in which the described invention functions will be readily understood. As the.

bales 5 are discharged from the baier I, said bales are pushed through the chute 6 for unloading onto the bed 1 of the trailer truck 8. When the baler i and trailer truck 8 are in motion, the drag of said truck tends to swing the'chute 6 upwardly and relieve the rods 2|, chains 26 and hook plates 21 of extra load resulting from the weight of the bales 5 on the chute 6.

The foregoing will, it is believed, suiiice to impart a clear understanding of this invention without further explanation.

Manliestiy. the invention, as described, is susceptible oi modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claim.

What is claimed is:

In combination, a tow vehicle, a trailer vehicle, a discharge chute extending from the rear end of the tow vehicle over the front end of the trailer vehicle and having a front end pivotally mounted on said rear end below the same whereby said chute is vertically swingable into upwardly and rearwardly inclined position, flexible means for sustaining said chute in said position against sagging. and means to couple said trailer vehicle to the bottom of said chute in the rear of the axis of swinging movement thereof and below said axis whereby the drag of said trailer vehicle will tend to swing the chute upwardly.
